METALLIC ROOFING.

SPECIFICATION forming part of Letters Patent No. 364,072, dated May 31, 1887.

Application filed October 22, 1886. Serial No. 216,967. (No model.)

To all whom it may concern:

Be it known that 1, ANDREW WIGHTMAN, of Peekskill, in the county of Westchester and. State of New York, have invented certain new and useful Improvements in Metallic Roofing; and I do hereby declarethe followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in metallic roofing; and it consists in plates which have their upper and lower edges turned over in opposite directions, so as to catch in corre sponding folded edges upon other adjoining plates, and which are provided with a rib or flange upon their outer sides, and which extends nearly across the plate, and with convex or raised portions at their other ends for the purpose of catching over ribs upon the next adjoining plates, as will be more fully described hereinafter.

The object of my invention is to produce a metallic roofingplate which can be quickly and readily laid, and'which will form a tight and reliablejoint when in position.

Figure l is aperspective of one of theplates by itself. Fig. 2 shows several plates secured together.

A' represents a square or oblong metallic roofing-plate, which has its two edges B O folded over 'in opposite directions for the purpose of being locked or joined to other plates which are similarly constructed. At a suitable distance from the outer end of the plate is formed a rib or convexed part, D, which projects from near the lower edge of the plate nearly to the edge of the top fold, and which rib or flange catches under the raised convex portion F, which isformed upon the end of the next adjoining plate. ,Each plate is struck up, as shown, so as to'form the ornamental p01 7 tions G H, which correspond to the raised portion F, and thus prevent the plates from ap- 5 pearing disfigured, as they. otherwise would do without the parts G H. These raised or beveled edges extend at right angles to each other around the lower corners of the plates in the form of the letter L. The edge of that g end where the raise F is formed comes down upon the top of thenext adjoining plate and forms a tightjoint therewith.

In putting the plates together it is only necessary to see. that the turned-over edges B O catch under the corresponding parts of the nextadj oining plates, and that the raised parts F come directly over the ribs or flanges D. These ribs or flanges prevent the rain from being driven under the edge of the plate, and thus assist in forming atightjoint. The lower corners of the plates extend in a horizontal line across the roof, which causes the raised parts 13 G H to give an ornamental appearance to the plates, and thus add greatly to their appearance.

The edges of the plates, bei ng niply lapped,

lock easily without cutting the corners, and are laid with the corners to a horizontal line,

while the seams run diagonally across theroof and the water runs away from the seams.

Having thus described my invention, I

claim- A metallic roofing formed of roofing-plates A, having their edges B C folded or turned
